Sadly I doubt sound quality is an issue for many Sat radio listeners. The average Joe is more than willing to trade sound quality for convenience or variety. As when CD's were traded for MP3's (or earlier, the trade off of LP's for cassettes). Kind of leaves those of us who value quality audio in the cold. One of the major selling points of XM (for me, at least) in the early days was the audio quality (which was superior to Sirius at the time). I'd imagine as compression technology improves, the focus will still be cramming more channelsinto the lineup rather than improving audio.Now I find XM's sound tolerable (a 13 band in-car EQ helps), but definitely not CD quality. I think of it more like FM radio now, only the music is a lot better, and there's more of it. My more critical listening is reserved for CD, SACD, and DVD-Audio. As long as XM programming doesn't start sounding like FM, I'll keep it around.
